This invention relates to Vimprovements in wall fixtures, and more particularly to Wall fixtures of the type commonly used in hospitals, having louvers to direct the rays of light from the fixture over a selected part of the room, usually the floor, to provide sufficient illumination for the nurse to` be able to safely walk about the room, and to prevent irritation of the patient by Adirect light in the path of his eyes. Y

It is customary in corridors to arrange such fixtures flush with the wall of the room at a distance of three to four feet from the floor, known as tray height, and, in use in bed rooms and in theatres and other public buildings, they are located at various distances from the floor to meet the different requirements. Such fixtures have also been customarily used to `illuminate stairways. Y

It has been customary to provide stationary louvers in the wall fixture to direct the light rays, the louvers being permanently fixed at the angle believed tobe correct, before installing the fixture.

It has been frequently found, after installing the fixture, that the louvers have been set at the wrong angle, or that theorigmal location for the fixture cannot be used, and that it must be positioned higher or lower than originally planned, because of the interference of some part of the building, so that the lighting effect obtained is improper.

An object of myinvention is to provide, in a wall fixture, adjustable louvers and means for adjusting the angle of the louvers minutely to provide for every practical vrange of adjustment desired.

Alfurther object of my invention is to vprovide means, operable from the exposed face of the fixture, for adjusting the angle of the louvers.

Another object of my invention is to provide a novel construction for mounting the louvers and adjusting means on a single base which may be readily disengaged from the installed fixture box and swung clear of the same, for access to the interior of the fixture box and to the louvers and their adjusting means. Y

These and other advantageousk objects, which will later appear, are accomplished by the simple and practical construction and arrangement of parts hereinafter described and exhibited in the accompanying drawings, forming part hereof, and in which:

Figure l represents a perspective View of the corner of a corridor provided with a wall fixture embodying lmy invention, the hidden Y fixture box being represented in dotted lines. l v

Figure. 2 represents a rear` elevational shown in Figure'l, on line X-X-v i Figure 3 represents a vertical transverse view of the face plate of the wall fixture sectional view taken on lines 3--3 of Fig- 1 ure 1, in the directionindicated by the arrows, showing the louvers in fully closed position.

Figures 4 and 5 represent similar but v fragmentary views showing the louvers in a half shut and in a fully open position,- respectively.

Figure 6 represents a Vvertical transverse sectional View taken on lines X-X of VFigure 1 in the direction indicated by the arrows.

Figure 7 represents an enlarged perspective fragmentary view showing indetail'my improved louver adjusting fmeans. My device consists, essentially, of the open base member l, provided with oppositelyarranged upstanding louver-retaining side brackets 2 2 formed integral therewith or secured thereto in any desired or convenient manner, and havingaligned apertures 3 to pivotallygreceivel the reducedf pivot ends 4 4 of thelouvers 5.v The louvers`5 are also provided with fulcrum pins 6, loosely passing through a` fulcrum plate 7, whereby on the longitudinal movement of the fulcrum plate 7, the louvers A5 may be swung, in unison, into a whollyl or partly closed or open position. v

The fulcrum plate 7 is moved in either direction by a member 8, (see Figures 4: and 7), which is shown to comprise a screw 9, vpassing through an opening 10 in the face '30 into open or closed position.

plate 11 andl having ahead 12 which may be enlarged to facilitate movement thereof resting in a countersunk portion, in the face plate 11, in open communication with the opening 10. The screw 9 passes loosely through a reenforcing boss laat the inner side of the face plate 11, and is provided,

Y immediately above the boss 14, with a nut 15 rigidly secured thereto, to vhold the screw 9 in position in the face plate 11 while it is threadedly engaged with the linternally threaded block 16.

The internally threaded block 16 is Aconnected to the fulcrum plate 7 by a link 17, which is pivotally secured, at opposite ends, to the fulcrum plate 7, and the block 16, (see Figure 7). An apertured strip 13 having aligned apertures 3 may be removably secured to the base member 1 instead of the bracket 2, or the bracket 2 may be provided with slots to receive the ends of the louvers 5 which may then pass through apertures in the strip 13. Y I

To move the louvers 5 toward either their open or their closedposition, the screw 9 is turned to the left or right, sothat the block 16 will be threadedly engaged by and move vertically on Vthe screw 9, drawing the fulcrum plate 7 ,connected thereto by the link 17, in the direction to move the louvers 5 The particular arrangement described for Y moving the fulcrum plate 7 is very desirable because itpermits of very iine and accurate adjustment of the angle ofthe louvers but it is within the scope of my invention to utilizeother structures, operable from the outside of the face plate 114 and operatively connected with the louvers 5 toaccomplish the same results. Y

The fulcrum pins 6 rest withinrecessed portions 18 in the bracket 2 (see Figure 3), whenthe louvers 5 are in their closed position.

The base member 1 is provided Ywithinwardly curved,'upstanding deflecting plates 19-19 arranged parallel with and adjacent to the uppermost andlowermost louver, respectively, to prevent the direct passage of light from the extreme points covered by said deflecting plates 19-19. c v

The face plate 11 carries the screw 9,.the other parts being self-contained on and carried bythe Ybase member 1`. To assemble the parts, the screw 9`is threaded into the threaded block 16, andV after the upper part of the screw 9 has passed therethrough, a pin 20.is'preferably passed through the end of the screw to prevent excessive threading thereof in the other direction.

A glassl panel 21 is placed on the inner Ysideof the face plate 11 to bemarginallyY confined by the internallyV threaded lugs 22 on the inner 'side of the face plate 11 (see Figure 2), and then` the base member 1gis swung over the glass panel 21, the apertures face plate 11 is preferably grooved toA receive a tubular packing 27 to fill space left by indentations orirregularities in ,the wall W' to which the fixture is secured, preventing the escape of light and entrance of foreign matter through lsuch space.

rIhe foregoing disclosure is to lbe regarded as descriptive and illustrative only, and not as restrictive or limitative ofthe invention,

of which obviously `an embodiment may be constructed including many V.modifications without departing from the general scope herein indicated and denoted lin the appended claims. Y Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a device of the character described, a basemember provided with an upstanding bracket having a series of spaced apertures, a strip removably ber opposite said aligned apertures, and a plurality of louvers provided with reduced ends Vloosely passing secured to said base mem-` bracket and provided with through the apertured portions of saidV bracket and strip, and a'fulcrum plate provided with apertures, said louvers being further provided with fulcrum pins extending beyond said bracket and loosely passing throughY the apertures in the fulcrum plate, said bracket having a series of spaced recessed portions to receive the. fulcrum pins when the louvers are moved to theirclosed position. f

2. In a device of the character described, an openface plate provided, on one side thereof with a plurality of upstanding lugs, glass panel positionedv on the face plate and marginally confined thereon by said lugs, a base member provided with pivotally movable louvers, means'passing through said base member and in engagement with said lugs to removably secure said'base member over said glass panel and to said face plate,

and a rotatable member passing through said face plate and base member operatively connected with said louvers .and 'rotatable from the outer side of saidfface plate, to move Vsaid `louvers in either direction, the marginal edge of said face platev being grooved, and a tubular packing fixed in the grooved edge of said face plate to prevent the escape of lightbetween the edge of the face plate and Wall to Which the device is secured. v Y 3. In a device of the character described, a base member provided With oppositely arranged upstanding members having a series of spaced apertures, a plurality of louvers provided With reduced ends loosely passing through the apertured portions of said upstanding members, and a fulcrum plate provided with apertures, disposed adjacent one of said upstanding members, said louvers being further provided with fulcrum pins extending beyond said upstanding member and loosely passing through the apertures in the f'ulcrum plate, said member having a series of spaced recessed portions to receive the fnlcruni pins When the louvers are moved to their closed position.
